- Abstract
Thirteen genera of plant parasitic nematodes associated with rapeseed, peanut, soybean and sunflower oil crops were recovered from ten governorates in Egypt during the 2000-2003 growing seasons. Helicotylenchus, Hoplolaimus, Meloidogyne, and Pratylenchus were found occurring with high population densities, frequency of occurrence and prominence values. Other nematode genera as Criconemoides, Heterodera, Hemicycliophora, Longidorus and Rotylenchulus differed in the previous parameters in the different surveyed localities. Most of the surveyed peanut and sunflower fields had populations of over 200 individuals of Meloidogyne spp., the main pest of these crops, per 200 g soil. Identification of Meloidogyne spp., indicated that only Meloidogyne javanica was the dominant species from all peanut root samples collected from three Governorates in Egypt. The differences in nematode parameters in different surveyed localities are discussed here.
